Die Casting Mould Improve Follow-up Efficiency

Die Casting Mould production often encounter new product development and the renewal of the old Die Casting Mould, due to the particularity of die-casting casting production process, in general, the quality of the casting and the quality of the external quality depends on the casting of the production process; such as metal Liquid temperature, pressure, speed and speed switching point. But most of the cases are also closely related to the design and manufacture of the Die Casting Mould. The influencing factors of the Die Casting Mould include the number of cavities, the design of the pouring system, the type (position and size) of the gate, and the structure of the casting itself. Therefore, in order to avoid the Die Casting Mould design caused by the casting defects, while the Die Casting Mould making some of the problems to be verified and amended; it is necessary to complete the Die Casting Mould to test the Die Casting Mould.

1 Die Casting Mould Die Casting Mould test purpose

The main purpose of the test mode is to find the optimal process parameters and Die Casting Mould modification program. Even if the material, machine settings or environmental factors have changed, still able to ensure that the Die Casting Mould can be stable and uninterrupted mass production of qualified products, to maximize the Die Casting Mould "adaptability", not just to get a few good Of the test sample.

1.1 to find out the problem of Die Casting Mould

Die Casting Mould factory to complete the production of the Die Casting Mould, are hoping to be a "adaptable" very good (that is, forming parameters or process conditions wide) Die Casting Mould. But often due to design considerations or the production process is not in place processing, often there will be some problems, such as the size of the ultra-poor, local transition is not smooth, inappropriate structure, etc., resulting in casting failure or Die Casting Mould test production can not be carried out The Therefore, if the Die Casting Mould is completed directly after the mass production, there may be a lot of waste loss. The test mode is to find out the Die Casting Mould point of the most simple, direct and effective way.

1.2 to find the best Die Casting Moulding conditions

In the course of the test mode, the test personnel can find a set of the most suitable process data, and the group of data in the mass production, as set the machine parameters of the default value, according to the set of data to adjust the Die Casting Mould mass production of the most Good process conditions.

1.3 verify CAE auxiliary design, improve follow-up efficiency

CAE analysis software, is based on the real machine specifications, real alloy performance and similar external environment, with computer simulation, calculate the simulation results. Die Casting Mould design staff according to the simulation situation, the Die Casting Mould design to make the appropriate correction; in the real machine test mode can be directly as the default data input value, test personnel can test the Die Casting Mould design is not considered ill At the office. You can compare the defects of the test module with the simulation results, and provide the basis for the follow-up simulation parameter setting.

Casting production of molten metal in the amount of castings on the quality of the casting have a certain impact, generally with the pressure chamber fullness (referred to as fullness) to describe the size. The chamber fullness is a data that should be accounted for at the beginning of the Die Casting Mould design. Full of over the General Assembly led to the beginning of the punch metal molten metal from the pouring spill, both the waste of metal liquid, there are some security risks; full degree is too small, the upper part of the pressure chamber is too large, easy to move into the molten metal So that the casting hole defects; at the same time, the metal liquid attached to the lower part of the pressure chamber heat exchange is also accelerated, easy to make the surface of the molten metal quickly solidified to form a condensate layer; this layer of condensation in the process of crushing, Forming a major source of oxide inclusions for castings.

Metal die-casting with high production efficiency, save raw materials, reduce production costs, product performance and high precision, in the production of a wide range of applications.

The working surface of the die-casting Die Casting Mould is directly in contact with the liquid metal, which is subjected to high-pressure, high-speed flow of liquid metal erosion and heating. After the workpiece is deDie Casting Moulded, it is subject to rapid cooling. Therefore, thermal fatigue cracking, thermal wear and hot- Die-casting Die Casting Mould common failure form, so the requirements of die-casting Die Casting Mould with hot and cold fatigue resistance, high temperature strength and toughness, resistance to liquid metal erosion performance, high heat resistance and high thermal conductivity, good oxidation resistance And high hardenability and wear resistance.

According to the characteristics of die-casting process combined with non-ferrous metal grades, the first rough design, and then start the Die Casting Mould design. For some of the structure does not meet the die-casting process, should communicate with customers in a timely manner, in consultation with the customer on the basis of further amendments. Japan's three well-known motorcycle brand R & D departments are at the beginning of the development to focus on grasping the surface inspection of this off, so to avoid development losses, reduce development time.

Die-casting Die Casting Mould design and non-ferrous metal grades related. In particular, ADC6 (JIS standard) aluminum alloy, the pouring system structure and draft angle and ordinary aluminum alloy is different, should be based on its poor mobility, high temperature and other characteristics of appropriate treatment. Japan has a large number of applications in high-strength ADC6 aluminum alloy, while the domestic application of less. ADC6 aluminum alloy die-casting Die Casting Mould common problems are: Die Casting Mould life is short; stripping resistance, easy to deformation, drawing die, the workpiece is easy to produce cracks at the top; poor mobility, easy to produce patterns, cold separation; Die Casting Mould protruding parts prone to cracks, In the design process should be in advance to deal with.

Die Casting Mould production process determines the entire production process is a high temperature process, which, Die Casting Mould temperature is high, seriously affect the casting solidification and cooling rate, so that a single piece of production cycle is long, efficiency is hampered.

Now, the extensive use of Die Casting Mould temperature machine, by controlling the Die Casting Mould temperature in the Die Casting Mould temperature, flow and other parameters to control the Die Casting Mould temperature, improve the cooling rate, to achieve production efficiency.

The advantage of using the Die Casting Mould temperature machine is that it can effectively shorten the casting solidification time, improve the die-casting production efficiency, reduce the rejection rate and extend the die life.
